Whatsapp Business Cloud Disconnecting Periodically

Describe the problem/error/question

I'm experiencing periodic disconnections with the WhatsApp Business Cloud node. To resolve this, I need to navigate to Meta → Business Manager → Whatsapp → API Setup and generate a new access token.

Afterward, I have to resubmit the credentials in the WhatsApp Business Cloud node.

What is the error message (if any)?

Connection failed.
